You have to use the latest Pharo 3.0 version: http://files.pharo.org/image/30/latest.zip It looks like Spec isn't loaded in your image. I didn't add any Spec dependencies in the Configuration due than Spec is loaded by default in Pharo 3.0 Hope it will work :) 2013/9/5 Alexandre Bergel <alexandre.bergel(a)me.com> > Hi Erwan, > > I've tried to load your work using the configuration, but I got: > > This package depends on the following classes: > TreeNodeModel > TabModel > WorldModel > TabManagerModel > You must resolve these dependencies before you will be able to load these > definitions: > properties > uiPainter > activeTab > properties > uiPainter > isActive > panelMorph > properties > uiPainter > properties > uiPainter > > > Select Proceed to continue, or close this window to cancel the operation. > > Cheers, > Alexandre > > > On Sep 5, 2013, at 3:16 PM, Erwan Douaille <douailleerwan(a)gmail.com> > wrote: > > > Hi, > > > > The GSoC deadlines is 16 september.

Hi Erwan, I've tried to load your work using the configuration, but I got: This package depends on the following classes: TreeNodeModel TabModel WorldModel TabManagerModel You must resolve these dependencies before you will be able to load these definitions: properties uiPainter activeTab properties uiPainter isActive panelMorph properties uiPainter properties uiPainter Select Proceed to continue, or close this window to cancel the operation.

Without mapping you get Arrays and Dictionaries back, that you can then convert to your domain objects in the a next step. With mapping however, these intermediary representations are not used and maps or lists are parsed while creating and populating your domain objects directly, which should be more efficient. This does of course introduce the necessity of adding some form of static typing. >> > >

Yes we admit it and then? We are concerned to help people. Did you run the rules generated from 1.4-2.0 activity because we are creating to help people migrating. We are fthinking about having better support to automatically migrate code based on changes (but for that we need manpower). > And that Pharo users are at least one version behind you, and that they would like a bit of smoothness in the way it evolves... 3.0 gives directions; but a bit of backport to help with the transition would be, what, just friendly to your users.

Give us any ideas how to help you and we will. This is why I propose to even undeprecate certain key features if it helps providing more stability from the users side.

Some news of the UIPainter project

by Erwan Douaille

Hi, The GSoC deadlines is 16 september. It means than i have one week to fix bugs and implements some new features. The best way to find bugs is user feedbacks. I will be glad to fix many bugs than you will find. (many bugs found in 5 minutes with my mentor ...) Here is instructions to load UIPainter : *Gofer new* * smalltalkhubUser: 'ErwanDouaille' project: 'UIPainter';* * configurationOf: 'UIPainter';* * load.* *ConfigurationOfUIPainter load* Here is my blog: http://uipainter-gsoc.over-blog.com Thanks for testing, feedbacks and ideas :) -- Best regards, Douaille Erwan <douaille.erwan(a)gmail.com>
